Document overview

This document is the user manual for the Standard Software Driver (SSD) for single C90FL

Flash module. The road-map for the document is as follows.

Section 1.2 shows the features of the driver. Appendix B: System requirements details the

system requirement for the driver development. Appendix D: Document reference lists the

documents referred and terms used in making of this document. Appendix C: Acronyms lists

the acronyms used.

Chapter 2 describes the API specifications. In this section there are many sub sections,

which describe the different aspects of the driver. Section 2.1 provides a general overview of

the driver.

Section 2.2 mentions about the type definitions used for the driver. Section 2.3 mentions the

driver configuration parameters and configuration macros respectively. Section 2.4 and

Section 2.5 describe the CallBack notifications, and return codes used for the driver.

Section 2.6 and Section 2.7 provide the detailed description of normal mode and special

mode standard software Flash Driver APIs’ respectively. Appendix A: CallBack timings

provides the performance indexes.

1.2

Features

The C90FL SSD provides the following features:

•

Two sets of driver binaries built on Power Architecture instruction set technology and

Variable-Length-Encoding (VLE) instruction set.

•

Drivers released in binary c-array format to provide compiler-independent support for

non-debug-mode embedded applications.

•

Drivers released in s-record format to provide compiler-independent support for

debugmode/JTAG programming tools.

•

Each driver function is independent of each other so the end user can choose the

function subset to meet their particular needs.

•

Support page-wise programming for fast programming.

•

Position-independent and ROM-able

•

Ready-to-use demos illustrating the usage of the driver

•

Concurrency support via callback
